I have posted my water parameters and fertilizer dosing numerous times and many people here told me that that is difficult to have nutrient deficiency by dosing throughout the week these specific amount of ferts and a big water change at the end.co2 and drop checker at pale yellow.my eleocharis has grown only a few square inches the last couple of months and plant growth is stable but slow.plants are pearling.the tank is 29g and is lit by 2x28w t5 bulbs.if we assume that there is no nutrient deficiency can we safely say its the low light?I would increase the number of bulbs but the thing is that some people here told me that i actually have enough light..can I have your opinion on my lighting level?also I could change the one of the two bulbs to red/blue,how about this?thanks a lot.
